comment What's the problem with electrolyte imbalance and how do I mitigate it?
Intersting comment about Gatorade not containing enough electrolytes relative to the water. I was told exactly the opposite in a SOLO course. The instructor said the Gatorade acknowledges this in scientific circles, but for reason of taste and marketing make their drinks stronger than necessary. The instructor went on to recommend 1/2 strength by adding water. I use about 1/2 to 2/3 strength routinely, including hiking most of the day in the desert in summer, and it seems to work fine for me.

Whoever downvoted this, it would be useful to explain what you think is wrong, incorrect, confusing, misleading, etc.

@Masked: Cold weather is different. I hike around New England in the winter, and the issues are different. In the winter you can get dehydrated and not realize it. When it's hot you get thirsty. You do lose a lot of water when its cold, but much of that is in your breath so is pretty pure. You should always at least think about electrolytes, but that is much less of a problem in the cold.

@gerrit: My electrolyte incident was in the middle of the summer on the west side of the Tonto basin. That place gets pretty hot, and that was a hot day as I remember it. 115F is my best guess. The hottest I've encountered so far in AZ has been 121F according to the rental car. That was in the Kofa refuge. I was hiking then with my usual (by that time) diluted gatorade and felt fine.

comment How can you navigate without a compass or GPS
This is just plain wrong. Different species of moss and lichens grow on different sides of trees dependent on a lot of factors. At the northern end of a species' range it may well appear mostly on the south side of trees while other species in the same forest are on the other side or all around depending on local microclimates. Just forget about the moss myth, it will waste your time and keep you from observing the things you really need to pay attention to.

comment Can body-to-body rewarming be used as a last resort treatment of hypothermia?
@Chris: What I was referring to is when hypothermia has progressed so far that the body shuts down blood to the extremities in the last effort to keep the core alive. Toxins then build up in the extremities. The victim can be poisened by his own toxins if the extremeties are warmed first. The person needs to be warmed from the inside out in a medical setting. Keep in mind we're talking about sever hypothermia progressing immenently to death without medical intervention. If someone can drink warm liquid, by all means have them do it, preferably containing fast-metabolizable sugars.

comment What are the key sites to see on a short trip through Oregon?
Wow, that's a lot of stuff for 2 weeks. You'll need a vacation when you get back from this vacation. Also, most of the arches are in UT, not NV. There are lots of beautiful places in OR. Crater Lake? Mt Hood? Lots of other parts of the Cascades? The coast, mouth of the Columbia?

comment Can body-to-body rewarming be used as a last resort treatment of hypothermia?
I suppose if the alternative is the person will die, then there is little downside. However, it could actually make things worse for severe hypothermia. At that level, the body needs to be warmed from the inside out. If not, the toxins that have built up in the extremities can get you. This needs to be done in a medical setting. If someone is still concious, get some hot liquid in them, otherwise evacuate if possible.

comment How far is a reasonable distance for someone to hike on their first trip?
Weight training doesn't do much for hiking stamina. You want erobic exercise for that.
